abstract: OBJECTIVE
  To apply problem-based learning (PBL) in pre-job training of postgraduate students in department of endodontics.
  
  
  METHODS
  Thirty master degree postgraduate students of China Medical University were randomly divided into 2 groups, there were 15 students in each group. One group were taught with PBL method while the other group with lecture-based learning (LBL) method. The teaching effect was measured with examination and questionnaire survey. The data were analyzed by student's t-test using SPSS 11.5 software package.
  
  
  RESULTS
  There was no significant difference in basic knowledge, medical records writing, oral examination between the two groups (P>0.05). There were significant differences in case analysis, dental operation, theory examination, practical examination and total scores between the two groups (P<0.05). The PBL method was welcomed by master degree postgraduate students.
  
  
  CONCLUSIONS
  The abilities of postgraduate students can be developed by PBL method in different aspects. PBL achieves satisfactory teaching effect, and can be applied in pre-job training of postgraduate students.
